Presidente Piñera recebe o primeiro relógio atómico do ESO
O Diretor Geral do ESO entrega relógio histórico como símbolo de gratidão pelos 50 anos de colaboração entre o ESO e o seu país de acolhimento
15 de Novembro de 2013
Ontem, numa cerimónia que teve lugar no Palácio de La Moneda, o Presidente do Chile, Sebastián Piñera, recebeu o primeiro relógio atómico usado pelo ESO das mãos do Diretor Geral do ESO, Tim de Zeeuw. O relógio, que foi instalado originariamente no Observatório de La Silla do ESO em 1975, foi entregue como símbolo de gratidão pelos cinquenta anos de colaboração bem sucedida entre o ESO e o seu país de acolhimento. Em troca, o Presidente do Chile entregou ao Diretor Geral do ESO um magnífico volume que descreve a história do Palácio de La Moneda.
O relógio atómico Rohde & Schwartz foi o primeiro do seu tipo no Chile e, durante muito anos, o sinal horário deste relógio foi extremamente importante mesmo para além de La Silla, já que serviu como referência de tempo muito precisa, sendo sincronizado com a fonte horária nacional do Chile, fonte essa localizada no Observatório Cerro Calán em Santiago. Esta sincronização era feita através de um “transportador de tempo”, que era levado fisicamente de La Silla a Santiago, permitindo assim uma sincronização altamente precisa a intervalos regulares.
Pelo significado que este relógio atómico tem como forte laço entre o ESO e o Chile, o ESO decidiu oferecer este instrumento ao Chile, numa das últimas atividades do 50º aniversário, que celebram a relação entre o ESO e o país de acolhimento dos observatórios do ESO.
“Este é para nós um importante símbolo da gratidão pela colaboração estabelecida há mais de 50 anos com o Chile. Estamos confiantes de que, ao continuar o trabalho juntos, continuaremos no futuro a trazer enormes benefícios culturais, científicos e tecnológicos tanto para o Chile como para o ESO,” disse Tim de Zeeuw, o Diretor Geral do ESO.
Durante a cerimónia, o Diretor Geral do ESO fez-se acompanhar pelo Representante do ESO no Chile, Fernando Comerón e pela Chefe de Gabinete do ESO, Laura Comendador. O Presidente Piñera fez-se acompanhar pelo Secretário de Estado dos Negócios Estrangeiros, Alfonso Silva e por Gabriel Rodriguez do Ministério de Negócios Estrangeiros.
O relógio atómico contém vapor de césio numa cavidade de ressonância que controla uma frequência de referência que pode ser usada para manter o tempo de modo muito estável. Durante muito anos, este relógio forneceu o tempo muito preciso necessário para apontar os telescópios e fazê-los seguir o trajeto diário dos corpos celestes ao longo do céu. O sinal horário gerado pelo relógio era distribuído a todos os telescópios instalados no Observatório de La Silla e era igualmente enviado para visores digitais situados nos telescópios e nas salas de controlo, mantendo uma precisão superior a uma milionésima de segundo.
